Dr. Pimple Popper found a bizarre growth like a fingernail on a patient's head

The INSIDER Summary:

Dr. Pimple Popper shared a new video in which she removes a strange growth from a patient's head.

It looks like a hard, gnarled fingernail.

She suspects that it's something called a cutaneous horn.

YouTube dermatologist Dr. Sandra Lee (aka Dr. Pimple Popper) doesn't just pop pimples — plenty of her videos are dedicated to removal strange skin growths, like giant lipomas. One of her most recent videos might show the most bizarre growth the channel has ever seen.

This time, the site of the oozing lump has sprouted a growth that looks like a fingernail gone rogue.

"He had this cyst on his head, and it looks like something still wants to grow out of it," Lee said in the new video.

At first glance that "something" looks like it might be soft. But once it's been excised, Lee reveals that it's actually hard and nail-like. Skip ahead to 8:01 in the video and you can hear her tapping on it with her surgical scissors. (But be warned: The sound might make you shudder.)

Lee wrote in the video's description that thinks the growth is a cutaneous horn, which is a hard, usually benign growth made from a skin protein called keratin. She also sent it to a lab for additional testing to confirm the diagnosis.
